<br>I know that ECCO has datasets on PO.DAAC(<a href="https://podaac.jpl.nasa.gov/ECCO?tab=mission-objectives&sections=about+data" target="_blank">https://podaac.jpl.nasa.gov/ECCO?tab=mission-objectives&sections=about%2Bdata</a>) and in the ECCO Drive Web Interface (<a href="https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/" target="_blank">https://ecco.jpl.nasa.gov/drive/files/Version4/Release4/</a> ), but the data names and directory organization are quite different from those. I was wondering if there are any differences in the data downloaded from these two different locations, especially the OBP data I'm interested in.<div><br></div><div>Thank you for your kindly help!</div><div><br></div><div>Regards,</div><div>Wenlan<br><div><br></div></div><div>
